3mm AGNES SH OBE Patented Feb. 28, 1950 UNITED STATES PATENT OFFICE 2 ,499,115 niece roe Toner Agnes shone, Bismarck, N. iia'k. Application January 29, 1947; Serial No. 724,969 9 Claims. (oi. 4 99) This invention relates to toilet structures.

It is an object ofthe invention to provide a toilet structure arranged for association with a toilet fixture such as a seat wherein waste matter such as urine which is not properly directed into the toilet fixture will be caught and carried ofi, thereby eliminating puddles of accumulated urine on the floor adjacent and particularly in front of the toilet seat.

Another object of the invention is to provide a unitary structure upon which a standard toilet seat can be conveniently mounted, such structure preferably being countersunk in the floor so that its upper surface is level with the floor.

Still afurther object of the in-i rentio'n is to provide a unitary strucure such as that set forth above which has means for flushing the receiving pan so that it can be kept sanitary and odorless.

Still a further object of the invention is to provide a toilet structure of the type described which includes a receiving pan and a grill top which is so constructed that the receiving pan can be readily reached for cleaning purposes. I

The above and other objects and advantages of the invention will more fully appear from the following description made in connection with the accompanying drawings, wherein like reference characters refer to the same parts throughout the views, and, in which: &

Figure 1 is a perspective view with parts broken away of an embodiment of the invention;

Figure 2 is a plan view with parts broken away; and

Figure 3 is a section taken approximately on the line 3-3 of Figure 1.

In the drawings there is shown a floor pan 4 having a bottom 5 which slopes downwardly from each end to a low point 6 approximately at the longitudinal center of the pan. The pan is provided with suitable side walls 1. At the low point 6 is a drain outlet 8 from which extends a drain pipe 9 having a trap I0.

Resting on the top of the side wall I of the floor pan 4 is a grill H made up of a plurality of longitudinally spaced parallel bars I2, said bars preferably having relatively sharp vertical edges l3 so that any moisture dropping on the bars will readily flow down the sides thereof and there is no substantial upwardly directed surface upon which moisture can collect. The grill bars l2 are connected by means of transverse webs M which serve to brace the bars and keep them properly spaced. At a point adjacent the longitudinal center of the grill the structure is divided and connected by suitable hinges I5 so that the forward 2 portion of the grill can be raised to "expose the interior of the pan 4 for cleaning.

The stationary rear portion of the grill II has a toilet fixture support in the form of a plate l6 countersunk therein, the plate 16 being secured in the grill by any suitable means such as welding. Extending downwardly from the plate i6 isa waste pipe I! which preferably is permanently secured to said plate. Braces 18 extend in opposite directions upwardly and laterally to opposite side portions of the plate [6 to more firmly connect said plate and the waste pipe I 1. The waste pipe i1 is provided with a branch iii to whicl'i the rearward end of the near pan drain pi e 9 is secured.

Extending about the inside of the pan 4 is a flushing conduit 20 which is provided with a plurality of spaced water outlet apertures 2|. A supply ci'iduit 22 extends into the pan at the rearward portion thereof to connect with the conduit 20. In order to protect the outlets of the flushing con'duitZ-B' from dirt which might drop throughtlie grill ll there is provided a shield 23 which overlies the flushing conduit between said conduit and the underside of the grill H.

The means of supporting the pan 4 in a suitable opening in the floor 24 shown in Figures 1 and 3 is not disclosed, any suitable connection being intended. It is preferred, however, that it be mounted in such a way that the upper side of the grill II and the floor surface be at the same leveli V With the structure such as Shawn and described the toilet new 25 is mounted on and suitably secured to a toilet fixture supporting plate I6 with its outlet in communication with the waste pipe section [1, the latter being, of course, secured to a waste pipe leading to a sewer. When the device is installed the entire unit can be put into place and the only connection is that between the waste pipe I! and the remainder of the sewer pipe, the connection between the water supply conduit 22 and a source of water, and a suitable supporting connection for the flush tank 26. If any liquids fall around and particularly in front of the toilet fixture 25 they will fall through the grill II and be received by the pan 4. The liquids drain out through the outlet 8 and pipe 9, and the pan 4 can be periodically flushed by admitting water into the pan through the apertured flushing conduit 20. When scrubbing of the interior of the pan is necessary the forward portion of the grill 1 I can be swung up to provide access to the interior of said pan.

Location of the low point 6 of the pan 4 rearwardly from the front end of the pan provides a relatively short pipe connection between the pan outlet 8 and the waste pipe I l. The grill structure is of sufficient strength that it can support the toilet fixture 25 while at the same time the grill is relatively open.

With the structure such as that disclosed toilets such as those in public buildings or ones which are used by a large number of people can be kept much more sanitary than in the case of installations where the toilet fixture is mounted directly on a solid floor. There are no moving parts to cause wear except for the hinged portion of the grill, and, as a result, the structure is capable of long use without any attention except for occasional cleaning. Not only does the construction render toilet rooms much more agreeable to the users thereof, but it is an important factor in the reduction of the carrying of disease since obviously if a persons shoes become wet from accumulated pools of urine about a toilet fixture any bacteria in the urine on the floor will be picked up on the shoes.

While I have shown and described the structure as being one wherein the supporting grill is countersunk in the floor it is obvious that the same structure can be placed upon existing floors,

utilizing standard outlet pipe connections and giving a raised floor efiect upon which the unit is mounted.

It will, of course, be understood that various changes may be made in the form, details, arrangement and proportions of the various parts Without departing from the scope of my invention.

What I claim is:

1. In a toilet structure, a floor pan having a drain outlet, a grill supported by and lying over the upper portion of said pan, 2. toilet fixture support carried by said grill, a waste pipe section secured to and supported by said fixture support, and a floor pan outlet pipe connected to said pan outlet and to said waste pipe section to provide a unitary drain pan, grill, waste pipe section and pan drain pipe assembly.
